Works great for monitoring pit/food temperature changes over time. When you see the fan speed increase gradually over an hour, you know you need to add more wood. It also allows you to configure the controller. Only lacking a notification/alert capability. I would like for it to notify on temperature, but also when fan speed gradually increases, hinting that it is running low on fuel.
